SPECIFICATION forming part of Letters Patent No. 240,550, dated April 26, 1881.

Application filed September 22, 1880. (No model.)

To all whom it may concern Be it known that I, FRANCIS '1. SARGENT, of New York city, State of New York, have: invented certain new and useful Improvements in Forming and Applying Patterns or Designs for Decorating Articles of Glass and Similar Material, of which the following is a specifica- My invention applies to those modes of decorating glass or similar articles by processes of etching or cutting, more particularly etching,

, where the design is printed in a protective ink and transferred onto the glass article so as to expose the parts to be acted upon and protect the rest. The usual system of making the blocks in a thick waxy ink, (usually a mixture of lamp-black, wax, resin, andturpentine,) upon tissue-paper, the inked parts of the design rcpresenting those 'not to be acted on, and vice versa. This design is transferred to the article to be etched in the usual manner by first pressing the inked side of the pattern thereon, then rubbing the pattern on the back side with a flannel pad held in the hand, and finally moistening thepaper with water or a gentle caustic, and removing the same, leaving the inked design transferred upon the article. After this, all parts of the ground not covered by the ink of the design must be varnished or painted with a suitable protecting ink or varnish before the article is submitted to the process of etching.

The objects of my improvements are to so print the pattern or design as to prevent the necessity of the aforesaid varnishing or covering of the ground after the design is transferred, and also to apply or rub the transfer onto the article in a more rapid and perfect manner; and it should be here stated that the first improvement particularly contemplates and relates to patterns for articles of globular or irregularly-globular shape, such as gas or lamp globes, 8m.

Heretofore the designs or patterns for such shapes have been so printed that the inked ground extendsonly slightly beyond and following the external contour of the design and no more, the main part of the ground being left uninked. Hence all of this ground must be painted over with the protectingink or vartire field of the pattern.

nish before the article can be etched, thusconsumin g considerable time and labor-,as well as running the risk of brushing over portions of the design which should be left uncovered,and

thus producingdetective work.

My improvement herein consists in printing the pattern with an inky ground extending beyond and completely inclosing the design in segmental inked inclosures or sections, so that when the pattern is applied to the globular'ar-u ,ticle the edges of. said inked segmentswillz imeet or 'lap', and thus completely cover the ground, rendering it necessary to apply little or no subsequent protecting-paint thereon.

The second feature of my inventionconsists: in rubbing the pattern uponthe. article by. "pressing the same against a revolving brush, revolving at a speed to allow the brushesto: slightly yield, whereby thepattern becomes pressed upon the glass uniformlyand firmly at all points, and in a more rapid and perfect.

manner than by the mode heretofore used, as hereinafter fully set forth. Figure 1 of the annexed drawings illustrates the mode of forming or printing the pattern.

as above described, and Fig. 2 illustrates the mode of applying or rubbing it onto the article to be etched.

In Fig. 1 the. black portions represent, of

course, the ink of the design, the large black spaces beyond the figuring being the ground of the design, the whole being printed, in thick waxy ink, upon tissu-paper, in the usual manner. It will be observed, however, that the inky ground is not confined to the external contour of the figures in the design, but extendsbeyond them in broad segmental patches or sections, completely circumscribing the features of the design and covering nearly the en- The pattern is usually made sufficiently longto encircle the globe, so as to carry the ornament all around the same, and hence only a portion of the pattern is shown in Fig. 1; but the length of the pat tern is of course regulated according to the extent of the desiredornamentation. The

cording to the nature of the figuring in the design, as will be readily understood. These segments may also spring from each side of the equator, according to the nature of the design and form of the globe; but ordinarily the form and arrangement of the ornamentation on the globe calls only for the shape of pattern illustrated.

\Vhen the pattern is applied to the globe the paper is folded or creased at the gores between the inked segments, and these gores are usually cut out with a scissors, (but this is not essential,) thus allowing the inked segments to meet or lap so as to completely cover the ground of the globe, so that after thetransfer is made and the paper stripped off there is no necessity for any re-inkin g of the ground, except, perhaps, occasionallyon a mere line at the meeting-point of the segments, thus effecting a great saving of time and labor and producing more perfect work. The segments of the pattern are, of course, laid out by a predetermined. system, so as to include the fea tures of= the design to the best advantage and fit the globe for which the pattern is intended, and the divisions of the segments are arranged to come remote from salient features of the design, so as to completely preclude the possibility of brushing over the same by any retouching that may be necessary at the joint of the segments, however carelessly these touches may be applied. By this mode of forming the pattern the most elaborate or intricate designs may be used, such as figures, landscapes, 850., beside the plain floral design illustrated, and a perfect transfer and etching thereof may be secured with unskilled help, and hence at much less cost. After the inked side of the pattern is applied to the glass and the segments properly met thereon, as above described, the globe, with the adhering pattern, is now pressed against a revolving brush, as shown in Fig. 2, and slowly turned, so as to submit all portions of the pattern to the action thereof. The hairs. of the brush may be either of metal or bristles, preferably the latter, and the brush is preferably about twenty inches in diameter and'two or three inches wide on the periphery, the bristles being about two inches long. The brush revolves at aboutthirty revolutions a minute, so that the centrifugal force will not appreciably rigidify the bristles, leaving them elastic and yielding against the pattern and globe. By this means the pattern becomes rubbed upon the globe in avery perfect manner, as the elastic bristles press individually into the minutest intricacies of the pattern, forcing the ink thereof to adhere perfectly to the glass, which is assisted by the frictional warmth produced thereby, yet without the least tendency to tear or injure the pattern. In this way notonly is the transfer made more perfectly than by the flannel pad heretofore used, but in one-third of the time required by that crude device.

What I claim as my invention is- 1. A transfer-pattern of substantially the described kind for globular shapes, printed with an inky ground extending beyond and including the features of the design, in segmental patches or sections, adapted to lap or meet when applied to the globe, and thuscover the ground thereof, substantially as herein set forth.

' 2. The mode herein set forth of rubbingor transferring transfer-patterns of thedescr-ibed kind to articles to be etched, consisting in pressing the article, with the pattern placed thereon, against a brush moving at a speed to allow the bristles to yield and press elastically into the intricacies of the design, substantially as herein shown and described.
